When installing posts into the ground we would recommend using post mix. Post mix is a pre blended factory produced quick setting concrete available from most builders merchants.
It is important that they are dug along a completely straight line and the correct distances apart. Generally fence and trellis panels sit in between the posts, whereas the slatted panels sit to the face (front) of the posts. One way to ensure the posts are installed straight is to set up a string line along the proposed line of the fence.
As a general rule the posts need to be set approximately 600mm (2ft) into the ground. After the hole is dug place the post into the ground using a spirit level to make sure the front of the post is carefully aligned along the string line. Back fill the hole with post mix following the instructions provided on the bag. Adjust the post into position and support appropriately for approximately 10 minutes until the post mix sets.
